bcoz synapses occur in motor pathway and periodontal mechanoreceptors initiate the reflex if they get stimulated.

right mesiotrussive
right laterotrusive

bcoz mandibular 1 premolar lingual cusps are very short as compared to buccal cusps

role of calcium in activation of cardiac muscle ?
a. couple myosin n actin to form actinomyosin
b. activate myosin molecules so tat they interact wit actin filaments

During oxidative phosphorylation, proton gradient is created using energy from
a. ATP hydrolysis
b. reduction of NAD

Production of phosphoenolpyruvate carboxykinase is stimulated by
cortisol
insulin

bcoz mandibular 1 premolar lingual cusps are very short as compared to buccal cusps


so it wud b always buccal cusp tht cud break the lingual cusp nd tht too by left mediotrusive

which feature of max LI complicate the root planning?
masial concavity
distolingual groove

DL cusp of right mand 1 molar is fractured with opposing max molar during rt lateral excursion .most lokely location of interference?
lingual surface of max lingual cusp
facial surface of max lingual cusp
lingual surface of max facial cusp
facial surface of max facial cusp

Plzz explain ..

when viewed sagitally, which teeth will have long axis least perpendicular to occlusal plane?

i m almost sure about it becoz u see during right lateral excursion lingual cusps of rt max posteriors pass thru the lingual grooves of the mand rt post teeth...keeping that in view it shd be the only ans.if u try doing it in ur mouth
